Airplane engine selection by optimization on surface fit approximations
M. J. R. Healy, Janusz S. Kowalik, James W. Ramsay · Journal of Aircraft · 1975
A comprehensive engine/airframe screening methodology has been developed based on surface fitting and nonlinear optimization procedures. These procedures include the use of experimental design techniques, and a gradient-based method for nonlinear constrained minimization. The methodology has been programed for use on the CDC 6600 computer and has been successfully demonstrated on extensive test cases. One test case involved selection of an optimum airplane design using performance data for only 28 designs. A total of 256 designs were required to locate this optimum graphically.
